Detailed Description
In order to make the objects, technical solutions and advantages of the embodiments of the present application clearer, the technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application, and it is obvious that the described embodiments are some embodiments of the present application, but not all embodiments. All other embodiments, which can be derived by a person skilled in the art from the embodiments given herein without making any creative effort, shall fall within the protection scope of the present application.
After a website is accessed, a visitor accesses the website and firstly passes through a cloud WAF, the cloud WAF forwards a visitor request to a website server where the website is located, network source return refers to a process that the cloud WAF communicates with the website server, and source return nodes refer to servers or server groups which communicate with the website server and do not directly interact with the visitor.
Referring to fig. 1, fig. 1 is a flowchart of a network back-to-source method according to an embodiment of the present application, where the method includes:
s101: acquiring network information of a target website, and determining a back source node of a line same as the network information;
the step is intended to obtain the network information of the target website, and the specific information type and content contained in the network information are not limited herein, and may be related information participating in network back-to-source, which may include but is not limited to a domain name, an IP address, a port number, and the like.
In this step, it is also necessary to determine a corresponding back-source node, i.e., a back-source node of the same line as the network information, which is a back-source node applying the network information in the network back-source process. Taking the network information as the IP address of the target website as an example, any return-to-source node taking the target website as the access destination needs to include the IP address of the target website, so that the return-to-source node taking the IP address as the access destination is the return-to-source node with the same line as the network information.
In addition, as a preferred implementation manner of this step, the back-source node of the same line as the network information may be determined according to the operator attribution information of the network information. If the back-to-source node is determined according to the operator attribution information, the fixed back-to-source node accessing the domain name and the port number can be determined according to the domain name, the port number and the like of the target website. Specifically, the attribution information of the operator where the website IP is located is determined, for example, the attribution information may be any one of telecommunications, communications, and mobility, and then the back-source node on the same line as the operator where the website IP is located may be directly confirmed.
S102: after the source returning node executes the source returning task of the target website, downloading the target website and collecting downloading parameter information;
the method aims to collect the downloading parameters of each return source node to the target website. It should be noted that, downloading the target website by the source node refers to downloading the page information of the target website, which is characterized as the loading capability of the target website, and the shorter the downloading time is, the faster the target website is loaded. For the user end, the downloaded content of the target website is actually page information of a website page, and the return source node in this step downloads the content of the target website, which usually includes a website page frame, page data, and the like.
In the step, before downloading the target website by default, a source returning task of the target website is executed, namely, the communication connection between the source returning node and the target website is established. How to implement the back-source task of the back-source node executing the target website is not specifically limited, but the back-source node may send the scheduling instruction to each back-source node after determining the back-source node in step S101, and each back-source node executes the back-source task of the target website after receiving the scheduling instruction, and establishes a communication connection with the target website. On one hand, the back-to-source node determined according to the network information in step S101 can be ensured to be accurate, and on the other hand, preparation can be made for a subsequent testing process of the back-to-source node.
And after the source returning node executes the source returning task, downloading the target website and collecting downloading parameter information. The downloading parameter information is not particularly limited, and mainly includes any one of the time consumed by the request, the time consumed by the downloading, and the downloading rate of the website, or any combination of several of them. By request time, it is generally meant the time from when the user makes the access request to when the request response is obtained. Of course, those skilled in the art can also use other download parameter information to determine the back-to-source node with a fast request response and a high website download rate.
Furthermore, on the basis of the step, in order to avoid data inaccuracy caused by single downloading or network congestion and other reasons, the target website can be downloaded for a preset number of times, and the average number of parameter information in each downloading process is used as downloading parameter information. The target website is downloaded for multiple times, and the average of the parameter information in the multiple downloading process is taken as the downloading parameter information, so that the error is reduced.
S103: determining an optimal return source node according to the downloading parameter information;
this step is intended to determine the preferred back-to-source node based on the download parameter information. It is easy to understand that the download parameter information in this step refers to the download parameters of each back source node to the target website, and not to the download parameter information corresponding to one back source node or a part of back source nodes.
It is easy to understand that the preferred back-source node should be the back-source node with faster request response, higher website download rate or other parameters. Because the downloading parameter information in the previous step cannot be uniquely determined, the mode for determining the preferred source returning node in the current step is not limited, that is, the mode for determining the preferred source returning node is adjusted correspondingly according to the acquired downloading parameter information.
Taking the example that the downloading parameter information includes the downloading time consumption, the step may include the following three steps:
s1031: calculating a downloading rate according to the downloading time consumption corresponding to each source returning node;
s1032: arranging the downloading rate information in a descending order to obtain a rate queue;
s1033: and taking the return-source nodes with the preset number of the speed queues as the preferred return-source nodes.
Obviously, the higher the download rate, the better, so that the back-to-source nodes corresponding to the forward download rate in the rate queue are better than the back-to-source nodes according to the descending order. The predetermined number is not particularly limited and may be freely set by those skilled in the art. The following setting manner for the preset number provided in this embodiment may not only be applied to the selection process of the preferred source returning node when the download time is taken as the download parameter information, but also be applied to the determination process of the number of the preferred source returning nodes in other embodiments.
If the number of the back-source nodes is smaller than the first preset number, taking all the back-source nodes as preferred back-source nodes;
if the number of the back source nodes is larger than the first preset number and smaller than the second preset number, taking one third of the number of the back source nodes as the preset number, and taking the back source nodes with the preset number in the speed queue as the preferred back source nodes;
and if the number of the back-source nodes is larger than the second preset number, taking one third of the second preset number as the preset number, and taking the back-source nodes with the previous preset number of the rate queues as the preferred back-source nodes.
The first predetermined amount and the second predetermined amount are not limited. For example, the first predetermined number may be 5, and the second predetermined number may be 30. If the number of the back source nodes available for service is less than or equal to 5, all results are obtained; if the number of the back source nodes which can be served is more than 5 and less than or equal to 30, one third of the number is selected; if the number of the back source nodes available for service is more than 30, 10 preferred back source nodes are taken as the top cover. Of course, the preferred back-source node taken should be the front-in rate queue or the superior back-source node in other queues.
S104: and utilizing the preferred back-source node to carry out network back-source.
After the preferred back-to-source node is determined, the preferred back-to-source node can be used for network back-to-source.
Specifically, when performing network back-sourcing, the resolution direction of the service domain name in the internal DNS may be adjusted according to the preferred back-sourcing node, and a request is initiated to the service domain name by using the website domain name in the network information as a request header, and the request is connected to the preferred back-sourcing node to complete the back-sourcing operation. The internal DNS is mainly used for adjusting the resolution of the internal service domain name for the request of an external service node.
According to the method and the device, the website servers are tested on all the source returning nodes according to the provided network information of the target website, and the optimized source returning nodes are configured according to the real-time downloading parameter information, so that the website downloading efficiency of the optimized source returning nodes is ensured to be high, the source returning network based on the optimized source returning nodes is established, the network source returning is enabled to preferentially adopt the optimized source returning nodes, the loading efficiency of the website can be improved, and the access experience of visitors is improved.
As can be seen from the foregoing embodiments, the present embodiment aims to determine a preferred back-to-source node and perform network back-to-source based on the preferred back-to-source node, so as to improve the network response speed and the website loading efficiency. It is easy to understand that, because the back-source node has the fluctuation of the node itself, that is, the performance of the back-source node is not stable, for example, the optimal back-source node in the previous round has a large load due to multiple network back-sources participation, and may cause performance degradation instead, or even no longer load the optimal back-source node standard. Therefore, on the basis of the above embodiment, the back-source node can be periodically detected to obtain the current preferred back-source node. The frequency of the periodic detection is not limited, and once the detection is too frequent, the website is downloaded for many times, which easily affects the normal operation of the website. Or different frequencies are adopted according to time periods, higher frequency detection is adopted in the website access peak period, lower frequency detection is adopted in the website access valley period, and the preferred back source node is dynamically adjusted.
In the application process based on the above embodiment, since it is not necessary for the serving node to determine which back-source node is the determined preferred back-source node, in each network back-source process, the specific application process may be as follows:
s201: receiving a network access request, and configuring a back source node corresponding to the network access request;
s202: judging whether the currently applied back source node is the optimal node in the idle preferred back source node; if not, entering S203; if yes, executing network source returning;
s203: and selecting a preferred back source node from the preferred back source node set, and returning to S202.
The preferred back-source node set mainly includes the preferred back-source node determined in the previous embodiment.
